A non-aqueous secondary battery having low impedance and excellent electrical characteristics by supplying a positive electrode paint having improved dispersibility of a carbon material as a conductive auxiliary agent, and a method of producing an improved positive electrode paint having excellent production efficiency. I will provide a. In a battery having a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte, the positive electrode is produced using a positive electrode paint in which a carbon material as a conductive additive is dispersed by a strong shearing dispersion device. The blackness of the electrode is set to 1.20 or more. [Selection diagram] None |
